Flat Roof Waterproofing – Complete Renewal & Protection cover

Flat Roof Waterproofing – Complete Renewal & Protection

This project involved a full refurbishment and waterproofing of an existing flat roof area. The roof had worn surfaces, water-pooling issues and failing joints. Our team carried out a complete preparation, repair, and installation of a high-performance waterproof coating system, ensuring long-term durability and weather protection. The process included surface cleaning, degreasing, joint and edge reinforcement, full waterproof membrane application, and final sealing. The new finish provides a seamless, UV-resistant, weatherproof coating designed to protect the property for many years. This upgrade eliminates leaks, strengthens the roof structure, and improves overall property performance.
